TENSION DEVICE FOR /VIN'DING .AND REELING `IVLACI-IINES.

To all whom it may concern.'

Be it known that I, GEORGE L. RICE, a citizen of the United States, residing at Chicago, in the county of Cook and State or Illinois, have invented certain new and useful Improvements in Tension Devices for Winding and Reeling Machines, of which the following is a full, clear, and exact speciication.

Myl invention relates to tension devices for winding and reeling machines and more particularly to tension devices employed in connection with the supply bobbins from which the material is wound.

In winding and reeling machines where material is unwound from a bobbin,.and is rewound in the shape of a ball, as, for instance, i-n the case of balling machines, it has been found necessary to decrease the tension on the supply bobbin as the machine is started in order that the twine, yarn or other substance being unwound, may not be broken by the sudden starting of the machine.

It has also been found desirable to have a series of bobbins carried by a single reel, in order that time maynot be lost in the operation of the machine when one bobbin runs out and another is required. ,In this connection it is necessary that means be provided for throwing the tensioning means out of operative position, andl after a new bobbin is in place, for throwing the tensioning device into operative position. As this operation must be gone through with many times in a day, the time consumed is considerable and it is of course desirable that this time be reduced to a minimum in order that the greatest possible amount of work may be accomplished by a single machine.

The object of the present invention is to enable the operator of the machine to lessen the tension on a supply bobbin during the starting of the machine, and to enable the operator to easily and quickly throw the tensioning means out of operation when it becomes necessary to replenish the supply of material.

With the above object in view, my invention consists in a tension device adapted to cooperate with `a supply member and in suitable means, such as gravity actuated means for maintaining the tension'device in a plu-A rality of positions, such as operative and inoperative positions. This device may be manipulated, if desired, by any one of a Specication of Letters Patent. Patented July 26., 1921 Serial No. 214,960.

plurality of operating connections in such a manner as to enable the operator to control the position of the device from different locations with respect to the machine.

In the accompanying drawings I have illustrated my invention in connection with the frame of a ballingmachine, the balling mechanism having been omitted, since it forms no part of the present invention. It should be understood that this tensioning device is of general application and may be employed wherever it is desirable to lessen the tension during the starting of the machine, or to throw the tensioning device out of operation during the replenishing of the supply of material.

In the accompanying drawings,

Figure 1 shows a front elevational view of my invention;

Fig. 2 shows a si-de ,elevation looking to ward the right in Fig. 1;

Fig. 3 is a side elevation similar toFig. 2. showing the tensioning means thrown out of operation; f

Fig. l1 is a partial side elevation on a small scale, looking toward the left in F ig. 1; and showing the reel locking device; l

Fig. 5 is a detail view showing the rotary reel structure;

Fifi'. 6 is an enlarged detail of the supporting spindle for the bobbin, and

Fig. 7 is a detail view still further en showing the spring catch mechanism for holding the bobbin shaft in operative position.

The frame 10 of theballing machine has a rearwardly extending horizontal portion 11 which supports two upright standards 12 and 13. these Standardshaving U-shaped upper ends 14;. in which is'secured the shaft 15 for the tensioning device. The standards 12 and'13 are provided intermediate their upper and lower ends with journals 16 for the shaft 17 on which is mounted the rotary reel 18 which carries the supplybobbins. This reel` has a` central vsleeve 19, journaled on the shaft 17 and is provided at one end with radial arms 20, and at` the opposite end with correspondingly located radial arms 21. The arms 20 have pivoted lthereto at their outer ends the bobbin supporting spindles 22, which are arranged as shown in Figs. 5 an-d 6, to be swung outwardly for the doiiing of the empty bobbins andthe reception of the full bobbin.` The arms 21, as

illustrated in Fig. 5, are provided at their outer ends with sockets 23 which receive the bobbin spindles v22 when these spindles are in operative position on the reel.

In Fig. 7 I have illustrated a spring catch 24 for holding the spindle 22 in operative position. This catch is pivoted at 25 to the frame ofthe arm 21 and has a spring pressed detent 26 which engages a pocket 27 on the frame of the arm 21 to hold the catch in closedV position, thereby retaining the spindle in operative position. Y j

In order to secure a reel against rotation rwhen the material is being unwound` from the bobbins, I have provided a notched disk 28 which is secured to the reel shaft and rotates with the reel. This `disk is pro-vided on its periphery with notches 29 which are in substantial alinenient with the reel arms. Coperating with these. notches 29 is a pin 30 carried by an arm 31 pivoted at to thestandard A12. This pin rests in the notch and the weight of the arm with the'engagement of the pin with the notchl is suiiicient to prevent the reel from rotating `until the arm 31 is lifted.

The tensioning means is embodiedin a V-4 shapedbrake device 33 which rests on the materialV carried by the upper bobbin and this device as illustrated, comprisesvthree flatblades, two of theseblades being disposed on one side of the'material and the third being disposed on the opposite side.

It willV be understood that the number of these blades isimmaterial andv that the device would Voperate successfully if a single blade constituted each Vportion `of the V- i shaped member. This tensioning brake device 33 is pivoted to arms 34 carried by a sleeve 34 which is journaled on the shaft 15 above mentioned and forms a pivoted support for the brake. The shaft 15 has journaled thereon at oneend a lever 35 and adjacent the lever 35 sh aft 15 carriesl a sheave. d 36 and there is secured to this sheave on itsl periphery a chain 37 which is pivoted to a downwardly extending link 38.`` The lower end of this linfk is slottedfas shown at 39 andthis slot carries a pin 40 which in turn is carried by a lever 41 at the rear end thereof. `The opposite end of this lever `is connectd by a Din land'slot connect-ion to -a lever' 42 having a` foot tread 43 at its opposite and front end.y The lever 35 is secured-by a bolt or riyet 44 to. the sheave V36 and to anV eX- tension V45 on the sleeve 34'carried by the shaft 15, and thissleeve carries on its opposite venda U-shaped extension 47 to which is secured ay triangularplate 48.` This plateV 48 is provided on Vits outer surface with a flat bearing portionor track 49 atthe ends ofwhich. are disposed inwardly extending overhanging Y portions 50. A metallic strip or wire 5l is secured atits ends to these overl hanging portions 5() and extends "therebe-v 'reel, which may then be swung to such apowhich forms a cushion for a weight 58 slid-y ably mounted on the rod 54.

Having described the structure of the tensioning device, I will now describe brieiy the operation of the tensioning means as it is used on a reeling machine. i

Assuming first that the rotary reel is in the position of adjustment shown in Fig. 2, and that theV operator is about to start the machina-by placing his foot on the tread 43 of the lever' 42,Y a downward force is exerted on the chain 37 and rod 38, thereby rotating the sleeve 34 carrying the-tensioning device 33 which is lifted sufficiently 'to release the tension on the material being unwound, thereby enabling the operator toY start the machine without breaking the material being unwound from the .supply bobbin, but the action. is such that sleeve 34 and plate 48 cannot be rotated -by the bobbin from which the material is'being un-r Y wound is emptied, the operator lifts the handle35 thereby rotating the sleeve 34 on the shaft 15 and with the sleeve 34 the projection 47 .and triangular plate48 are-rotated. lVhen the lever 35 has been lifted suiiiciently and the` plate 48 has'been rotated about the shaft 15 beyond'a certain degree the pin '.52 and rod 54 carrying the weight 58 will slide on the track orbearing portion 49 and the weight will pull downwardly ou the plate 48 and will assist in rotating the sleeve 34,V the final positionof the parts above le-V scribed being'shown'in Fig. 3,. From the showing vin Fig. 3 it will bev clear that the weight 58 holds the tensioning device out of operation until the operatorswings the lever 35 in a downward direction, again rotating the plate 48 and sleeve 34 on the shaft. 15. Thus it will be seen that Athe weight :is utilized in maintaining the tensioning de- .vice in bothextreme positions Yof itsl adjustsition that a full bobbin isdisposedupper-V Y wardly to the Vdotted line position shownv in Figs. 5 and 6.after 4the catch 26 has been withdrawn, and a full bobbin may be placed in position on the spindle which will then be again swung inwardly and held in operative position by the catch. If the operator desires to throw the tensioning device 33 out of operation from the front of the machine, the levers 41 and 42 may be so proportioned that a downward pressure exerted on the tread 43 will rotate the sheave 36 and the sleeve 34 sufficiently to throw the plate 48 to such an extent that the weight 58 will complete its rotation to the position shown in Fig. 3. The main object, however, of the lever 42 and tread 43 is to enable the operator to temporarily lessen the tension on the supply bobbin during the starting of the machine.

although I have in the above speciiication described ene embodiment which my invention may assume, it should be understood that the device is capable of many modifications and that such modifications may be employed without departing from the spirit and scope of the invention as eX- pressed by the following claims.
